Explain the purpose of adding 6 M HCl to the aqueous layer with sodium benzoate. Draw the reaction between sodium benzoate and HCl.
Calculate the final temperature of 37 mL of ethanol initially at 11 degrees C upon absorption of 624 J of heat. (density of ethanol =0.789 g/mL).
A close chemical relative of the banned insecticide DDT is methoxychlor (C16H15Cl3O2). Methoxychlor is currently used as a home insecticide. Calculate the mass percent of oxygen in methoxychlor.
What is the probability of finding a particle of mass m in (a) the left-hand and one-third, (b) the central one-third, and (c) the right-hand one-third
A 2.00L buffer solution is 0.250M in HC2H3O2 and 0.250M in NaC2H3O2. Calculate the pH of the solution after the addition of 0.100 moles of solid NaOH. Assume no volume change upon the addition of base.
